Kev Tshuaj Xyuas Zoo ntawm Kev Kho Mob Kub rau Cov Phaj Puab Crusher

Rau kev tshuaj xyuas qhov zoo ntawm kev kho cua sov ntawm cov phaj puab tsaig crusher ua los ntawm cov hlau manganese siab, nws yuav tsum suav nrog kev tshuaj xyuas qhov nyuaj, tawg, carbide precipitation, decarburization, thiab lwm yam, thiab yuav tsum tau ua raws li cov kev cai lij choj. Rau cov qhov tsis zoo xws li qhov nyuaj tsis tsim nyog lossis carbide precipitation, cov tshuaj annealing thiab dej quenching yuav tsum tau rov ua dua, thiab yuav tsum tau them sai sai kom ntseeg tau tias qhov kub thaum nkag mus rau hauv dej ua raws li cov cai.

Nws yuav tsum tau sau tseg ntawm no tias decarburization ntawm castings yog qhov txaus ntshai: tom qab txias hauv dej, cov txheej decarburized hloov mus rau hauv cov qauv martensite, tab sis cov txheej saum npoo yog brittle heev nrog plasticity qis heev, thiab nws lub zog sib txuas nrog cov qauv austenite sab hauv yog pluag heev. Nyob rau hauv cov xwm txheej abrasive hnav, cov txheej saum npoo tev tawm sai sai. Tom qab dej txias, cov txheej decarburized dhau los ua martensitic hloov pauv, ua rau ntim nthuav dav, thaum cov txheej sab hauv ntawm cov hlau tseem yog cov qauv austenite. Kev ntxhov siab tshwm sim ntawm cov txheej saum npoo thiab cov txheej sab hauv, thiab cov nqi linear shrinkage ntawm ob cov qauv kuj sib txawv thaum lub sijhawm txias tom qab, ua rau nto tawg.
